## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__converter__inspect_file` `mcp__converter__list_converters` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `convert_file`

- The name "convert_file" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Convert a subtitle, transcript, caption, EDL, FCPXML, or Premiere .prtranscript file. Pass text file contents in `content`; pass binary files (.prtranscript) as base64 in `content_base64`. The filename extension drives format detection. Use `target` from list_converters to pick the output, or leave it as "auto" to get the default output for the detected format. Returns the converted file content (text formats inline; DOCX/ZIP as base64).
```

### `timecode_calculate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Parse an SMPTE timecode at a frame rate (including 29.97/59.94 drop-frame) and report its frame count and real elapsed seconds; optionally re-express it at another rate.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `inspect_file`

- The name "inspect_file" says "inspect": a word for reading.
- Tag private-data: The name "inspect_file" says "inspect" and "file": it reads files. The description's first sentence says "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Detect the format of a subtitle/transcript/EDL/FCPXML file and report what CutConvert would produce from it, without performing the conversion or using quota.
```

### `list_converters`

- The name "list_converters" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
List every conversion CutConvert supports (source format, output format, and the target id to pass to convert_file).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `converter`:

```json
{
  "permissions": {
    "allow": [
      "mcp__converter__list_converters",
      "mcp__converter__inspect_file"
    ],
    "ask": [
      "mcp__converter__convert_file",
      "mcp__converter__timecode_calculate"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__converter__list_converters`: private-data
- `mcp__converter__inspect_file`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:30:17.139Z, unchanged since 2026-10-22T14:30:17.139Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://cutconvert.com/api/mcp: tools/list returned 4 tools to an anonymous client, including convert_file (write), timecode_calculate (write)
